Ocean Floor Mapping and Analysis

The video tutorial guides students through the 'Mapping the Ocean Floor' lab assignment. It begins with an introduction to the lab and instructions on accessing the assignment. The tutorial explains how oceanographers use sonar to map the ocean floor and demonstrates using Excel to calculate ocean depth. Students learn to create and format graphs in Excel, label ocean features, and finalize their lab work. The tutorial emphasizes the importance of accurately labeling features like the continental shelf and abyssal plain.

What are the two ways to access the mapping the ocean floor lab assignment?

• Through a mobile app notification or a printed handout.

• By attending a live class session or downloading from the course website.

• By visiting the course materials section or using the course resource newsletter.

• Through the geological oceanography tab and a direct email link.

What technology do oceanographers use to measure the depth of the ocean floor?

• GPS

• Sonar

• Lidar

• Radar

What is the formula used to calculate ocean floor depth in the lab?

• Depth = Time + Velocity

• Depth = Velocity / Time

• Depth = 1/2 x Time x Velocity

• Depth = Time x Velocity

Which software is used to perform calculations and create graphs for the lab?

• Adobe Photoshop

• Microsoft Excel

• Microsoft Word

• Google Sheets

What should be labeled on the y-axis of the graph?

• Latitude

• Longitude

• Time in seconds

• Depth in meters

What title should be given to the chart created in the lab?

• Geological Oceanography

• Ocean Floor Map

• Sonar Data Analysis

• Ocean Depth Sonar Data

Which ocean floor features need to be labeled on the graph?

• Mid-ocean ridge, trench, and seamount

• Tidal wave, tsunami, and hurricane

• Coral reef, lagoon, and atoll

• Continental shelf, continental slope, and abyssal plain

What is one method suggested for editing the graph to add labels?

• Using a text editor

• Using a photo editing software like Snagit

• Using a spreadsheet formula

• Using a web browser

What is the purpose of labeling features like the continental shelf on the graph?

• To ensure the graph meets software requirements

• To increase the complexity of the assignment

• To provide a reference for ocean floor features

• To enhance the visual appeal of the graph

What is the final step in completing the lab assignment?

• Submitting the graph to the instructor

• Printing the graph for personal records

• Copying and pasting the graph into a Word document

• Emailing the graph to classmates
